I'm following blog post about using ELK stack. Machine for instalation is an amazon small Ubuntu instance.
I got to the point when I need to install Kibana service so I run:
sudo apt-get install kibana
Then I changed in /etc/kibana/kibana.yml
server.port: 5601
elasticsearch.url: "0.0.0.0:9200"
since I can get response from elasticsearch sudo curl 0.0.0.0:9200
then I run
sudo service kibana start
And after running sudo service kibana status I receiving:
x#ip-xx-xx-xx-xx:/$ sudo service kibana status
● kibana.service - Kibana

I am running Django dev server in docker with celery and redis on my remote host machine.
Everything works fine like 30 mins, and then redis starts falling into infinite loop while MASTER <-> REPLICA sync started
Here's the console output:

My docker-compose file:

I have no idea what's wrong here, 'cause on local machine everything works fine. I aslo tried apk-get update && apk-get upgrade, nothing changed

I need to automate yum update across a list of instances, I tried something like aws ssm send-command --document-name "AWS-RunShellScript" --parameters 'commands=["sudo yum -y update"]' --targets "Key=instanceids,Values=<target instance id>" --timeout-seconds 600 in my local terminal (MFA enabled, logged in as IAM user, can list all ec2 instance under all regions by aws ec2 describe-instances) got the output with StatusDetails": "Pending" and the update never took place.
I checked the ssm log after starting an ssm session on the target instance

I'm trying to deploy a simple ExpressJS app with Prisma ORM.
Here is the full project: https://github.com/oxyn/aws-codebuild/settings
I'm trying to build through Amazon CodePipeline. For build, I have selected Ubuntu (aws/codebuild/standard:5.0). For Elastic Amazon is using Amazon Unix as I know.
I specified binaryTargets:
generator client {
provider = "prisma-client-js"
binaryTargets = ["rhel-openssl-1.0.x"]
}
but still, I can't get data.
"error": {
"clientVersion": "3.0.2"
},
This is an error that I'm getting inside of try-catch and this is log from Elastic:

I'm generating Prisma in post_build section:
post_build:
commands:
- echo Build completed on `date`
- npm run generate
What I'm doing wrong?
I had the same problem.
I add the command "npx prisma generate" after npm install
I use Google Cloud Build to build GCP Endpoints which relies on openapi-run.yaml to define the API. I have a large JSON schema file of which I want to refer to in the openapi-run.yaml:
/testRef:
get:
summary: test for Reference
operationId: testRef
responses:
'200':
description: A successful response
schema:
$ref: "/workspace/src/models/myLargeSchema.json#/Account"
But when I run gcloud endpoints services deploy openapi-run.yaml --project myProject, it gives me an error saying
"OpenAPI spec in file {openapi-run.yaml} is ill formed and cannot be parsed: Unable to load RELATIVE ref: /workspace/src/models/myLargeSchema.json"
I double-checked using ls command and confirm that the schema file is retrievable:
- name: 'gcr.io/cloud-builders/gcloud'
entrypoint: 'bash'
args: [ '-c', 'ls ./src/models -la']
Output

Question
How can I write my openapi-run.yaml so that it can refers to my JSON schema in another file?
I have found out that calling for external references in NOT supporting in GCP Endpoints: https://cloud.google.com/endpoints/docs/openapi/openapi-limitations#external_type_references
You are using an absolute filename, not a relative one. Try dropping the leading /workspace/ from the path in $ref.

Does anyone have a clue what the error is about?
Furthermore, why the stack is created with success? (as also the specific resource?)
The error message in /var/log/cloud-init.log means that your UserData script exited with error status 1 rather than the expected 0.
Meanwhile, your /var/log/cloud-init-output.log contains this line:
ValidationError: Stack arn:aws:cloudformation:eu-west-1:248059334340:stack/test-elastic/9fc79150-0e8b-11e9-b135-503ac9e74cfd
is in CREATE_COMPLETE state and cannot be signaled
To your other question:
Furthermore, why the stack is created with success? (as also the specific resource?)
It is the normal behaviour of the stack to go into CREATE_COMPLETE state once the resources are created. The running of the UserData script doesn't by default delay this state.
Because you are using the cfn-signal, I assume that you have a requirement for the CREATE_COMPLETE state to be deferred until such time as you send the signal in UserData.
There is a good blog post on how to set this all up here.
But tl;dr -
You probably just need to add a CreationPolicy to your EC2 instance resource like this:
Resources:
EC2ESMasterNode1:
...
CreationPolicy:
ResourceSignal:
Count: 1
Timeout: PT10M
That says wait for 1 signal and time out after 10 minutes. Set those according to your requirements obviously.
